Emissions analysis of an SI engine with humidified air induction

Air Mass Flow Analysis for SI Engine: EGR and Scavenging

In order to lower the Nitrogen Oxides (NOx) concentration in internal combustion engine emissions and to improve performance, Exhaust Gas Recirculation (EGR) and Scavenging mechanism are introduced. EGR recirculates a fraction of the exhaust gas back into the cylinders, thus diluting the intake air. This lowers the maximum combustion temperature and, since the formation of NOx is heavily depend...

effect of bioethanol-gasoline fuel blends on an si engine exhaust emissions

in this paper, the effect of bioethanol- gasoline fuel blends on exhaust emissions of a four-cylinder spark ignition (si) engine was investigated experimentally. pure gasoline fuel was blended with various percentages of bioethanol (0, 20, 40, 60 and 85%), and the hc, co, co2 and nox exhaust emissions were measured at different engine speeds and two throttle valve positions (full throttle and 5...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
